Abstract:
A radio frequency package on package (PoP) circuit is described. The radio frequency package on package (PoP) circuit includes a first radio frequency package (306). The first radio frequency package includes radio frequency components (310 312 314 316). The radio frequency package on package (PoP) circuit also includes a second radio frequency package (308). The second radio frequency package includes radio frequency components (322 324). The first radio frequency package and the second radio frequency package are in a vertical configuration. The radio frequency components on the first radio frequency package are designed to reduce the effects of ground inductance.
Abstract:
In a multi-module integrated circuit package having a package substrate and package contacts, a die is embedded in the package substrate with thermal vias that couple hotspots on the embedded die to some of the package contacts.
Abstract:
An integrated circuit package includes a microelectromechanical systems (MEMS) device embedded in a packaging substrate. The MEMS device is located on a die embedded in the packaging substrate and covered by a hermetic seal. Low-stress material in the packaging substrate surrounds the MEMS device. Additionally, interconnects may be used as standoffs to reduce stress on the MEMS device. The MEMS device is embedded a distance into the packaging substrate leaving for example, 30-80 microns, between the hermetic seal of the MEMS device and the support surface of the packaging substrate. Embedding the MEMS device results in lower stress on the MEMS device.
